Abstract

trata-se de um dispositivo para criptografar (por exemplo, codificar ou decodificar) dados de vídeo que inclui uma memória configurada para armazenar dados de vídeo, e um criptógrafo de vídeo configurado para criptografar parâmetros de decodificador de referência hipotética (hrd) para cada subcamada de cada partição de fluxo de bits de um fluxo de bits de vídeo; e processar o fluxo de bits de vídeo com o uso dos parâmetros de hrd. o criptógrafo de vídeo pode criptografar os parâmetros de hrd na forma de um loop através dos parâmetros de hrd que são iterados para cada uma das subcamadas, e/ou índices para respectivos conjuntos de parâmetros de hrd para cada uma das subcamadas.It is a device for encrypting (for example encoding or decoding) video data which includes a memory configured to store video data, and a video cryptographer configured to encrypt hypothetical reference decoder (hrd) parameters for each sublayer. of each bitstream partition of a video bitstream; and process the video bitstream using the hrd parameters. The video cryptographer can encrypt the hrd parameters in the form of a loop through the hrd parameters that are iterated for each of the sublayers, and / or indexes for respective hrd parameter sets for each of the sublayers.
